A steel rod with thread connects or fastens two materials together. This means the steel rod must be strong under tension, especially where the thread is cut.
Our rod with thread features precisely cut Metric Standard threads, ensuring smooth engagement with nuts or similar fixings and the ability to transmit and hold all loads suitable for the diameter of the bar.
A 6mm threaded steel bar has a proof load of approximately 450kg, while a 20mm threaded steel rod has a proof load of 5000kg or more. A suitable safety factor must always be considered within these loads when choosing your threaded rods for a particular application.
Our threaded bars are made from BZP mild steel. BZP stands for Bright Zinc Plated, meaning the finished and screw-cut bar is electroplated with a thin layer of zinc to provide a moderate level of protection against corrosion, as well as a bright appearance.
BZP metal is suitable for uses where the material won’t be exposed to long-term harsh conditions, such as enclosed, indoor or sheltered uses in mild climates. In prolonged outdoor or exposed use, the zinc coating will gradually wear away and the steel will start to corrode.
